Fourth seed Stefanos Tsitsipas edged world number one Daniil Medvedev 7–6(6) 3–6 6–3 in an absorbing semifinal at the Cincinnati Open on Saturday to set up a summit clash with Borna Coric after the Croatian’s 6–3 6–4 win over Cameron Norrie.
Tsitsipas saved a set point in the opening tie-break to take the lead but collapsed in stunning fashion in the second set, falling behind 5–0 before narrowly avoiding a bagel.
